IMPROVEMENT lN TUCK-FOLDING ATTACHMENTS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 169,629, dated November9, 1875 application filed June 2, 1875.

To all whom it may concern:

Be it known that I, GEORGE L. DU LANEY, of the city, county, and Stateof New York, have invented certain new and useful Improvements in aTuck-Foldin g Attachment for Sewing-Machines; and I do hereby declarethat the following is a full and exact description of the same,reference being had to the accompanying drawings and letters ofreference marked thereon.

The nature of my improvement consists in constructing an ordinary sewingmachine gage with a longitudinal aperture through its entire length, andproviding the same with a detachable, flexible, graduating guide forregulating the spaces and guiding the folds for tucks While the latteris being stitched to any desirable width.

Figure 1 shows the flexible guide detached. Fig. 2 shows a perspectiveview of my gage with the flexible guide-piece in position.

The gage A is cast of any desirable metal, and the aperture rl, through.which the flexible graduating guide-piece B is adjusted, is cored out tosuitable dimensions in the usual way. The slot 2 is provided for thelateral adjustment of the gage A in measuring any desirable Width oftuck, and is secured in position to the cloth-plate of the-machinebymeans of the thumb-screw in the usual manner. The gage A is providedat its rear end With a small point, 0, which extends through to theinside, the object of which is to engage with the corrugations Z formedon the upper bent end of the flexible graduating guide-piece B, as it isadjusted laterally to the edge of the tuck already stitched to suit thewidth of space between the tucks while the latter is being stitched. Theautomatic vertical action of the piece B serves readily to adj ustitself to suit any thickness of goods. Binding of any Width or thicknessmay be sewed on by adjusting the gage A to the edge of the goods, andthe lip 19 to the edge of the binding, which will secure it in properposition while being sewed. Thus it will be seen that by thisconstruction I combine in a very simple manner the qualities of a gage,a tuck-folder, and a binder.

I claim- In combination with the gage A, having the aperture d and point0, the flexible graduating guide'piece B, provided with corrugations Z,all as shown, and for the purpose specified. GEORGE L. DU LANEY.Witnesses: v J osEPH HARDoAsTL A. ZELLAs.
